it is correct i took the quiz

l

Ocean waves are the mechanical wave.

Explanation :

The waves that require medium to transport energy from one location to another is called the mechanical wave. There are two types of mechanical waves i.e. longitudinal wave and transverse waves.

The ocean wave is a longitudinal wave.  

Microwaves used to heat food, x rays and the light from a flashlight are electromagnetic waves. These waves require a medium to propagate.

Hence, the correct option is (A) " ocean waves ".
